Beyond the Padlock 🔒: Demystifying TLS - Part 1

Lost In Abstractions • 1 HN point • 11 Apr 24
🕹 Technology Security Encryption Networking
  1. TLS encryption involves various components like digital certificates, public key cryptography, symmetric key encryption, and cipher suites.
  2. A TLS handshake process includes agreeing on a cipher suite, server authentication, session key exchange, and establishing a secure connection.
  3. Version differences in TLS, such as TLS 1.2 and TLS 1.3, impact the handshake process, with features like forward secrecy in 1.2 and shorter handshakes in 1.3.

Oracle-based Conditional payments on Bitcoin

LN Markets’ Newsletter • 58 implied HN points • 16 May 23
🕹 Technology Cryptocurrency Bitcoin Encryption
  1. Oracle-based Conditional payments introduce a new way to handle conditional payments on Bitcoin by using oracles to attest to real-world events, allowing contracting parties to claim funds based on these attestations.
  2. Conditional payments rely on a third party for attestation, but in Oracle-based payments, the third party only attests events and does not execute contracts, improving security and trust in the process.
  3. Verifiable witness encryption plays a crucial role in setting up Oracle-based Conditional payments, ensuring that contracting parties can trust the oracle's attestations and claim funds accordingly.
